The results show that the parent fishes.of Mystus macropterus have a higher survival rate and better gonad development. By mixed culture with normal species fishes in pond.From 1992 to 1994,the survival rate of parent fishes are 100%,78.4% and 90.6% respectively.The maturity rate of female are also 73.3%(1993) and 70.6%( 1994). At the mixed culture Pond, the Parents may growth very well even needn't feed specially.The increment of body weight of parents is 0.62 g per day in 1992 and 0. 57 g per day in 1994. |
